2001 Hypertech power programmer

It was on a 2001 gmc sierra 5.3. The difference in my opinion comes in at the higher shift points. It lets you shift at 6000 rpms and thats what most of our trucks like. I will call him up and let him know since he doesnt have the time to frequent the site as much as many of us.
It was removed from the pick-up because they added a supercharger and went with a nelson tune.
